DEVICE FOR EXPRESSING BLOOD FROM MEAT.

To all whom it may concern:

"for expressing blood rom meat, and the object of the invention is toprovide an improved device of the present character which shall beextremely simple in construction, cheap to manufacture, and capable ofreadperforming the service for With the above and other objects in view,the invention comprises the construction, arrangement and combination ofparts as now to be fully described and hereinafter speci ficallyclaimed.

In the accompanying drawing forming a part of this specification, I

Figure 1 is a perspective view of the device; and

Fig. 2 is a sectional view thereof. The device of this lnventlonconsists, broadly, of a casing adapted to carry rolls 7 which areadjustable from and toward each 14, so that the meat which 35" other andwhich are capable ofrotating in opposite directions, and a containeradapted to be removably attached to the casing in position to receiveblood expressed from has been passed between the .4- rolls. The casingcan be of any desired configuration. I prefer to make it as shown in thedrawing and as now to be. fully set forth, 1O denotes a continuousconical wall leading to an opening 11, and 12 denotes side wallsextending upwardly from the conical wall. The side walls are shownparallel with each other. The portion of the casing which extends belowopening 11, denoted by 13, 1S internally threaded as indicated at 14. 15denotes a container adapted to receive the expressed blood. Thecontainer can be attached to the casing in any deslred manner to receivethe blood, which, as will be understood, will pass through opening 11. Ipreferably provide the mouth of the container with a thread 16 adaptedto engage thread container can be removably attached in position toreceive the blood.

A roll 17 extending across the casing and located above opening 11, isfixedly mounted Specification of Letters Patent. Application filedSeptember 27, 1920.

to turn. in the side walls of the casing, roll 18 extending across thelng screw brackets whlch are cated at the outer sides of the side Wallsof the casing and are adapted to rotatably carry the opposite reducedends of roll 18. Adusting screws 21, threadably mounted in the upperends of the side Walls, respectively, or in extensions of said sidewalls, as indicated generally at 22,'are adapted to move the adjustingscrew brackets to the desired position of roll 18 with respect to roll17. The connection, denoted 23, between each adjusting screw and itsbracket is'of such for rotating the adjusting example, thefinger piecesdenoted 24.

25 denotes a gear which is fixed to an end of roll 17 and islocated atthe outer side of one of the side casing, and 26 denotes a gear which isfixed to an end of roll 18 and is located at the outer side of one ofthe adjusting screw brackets. A driving screw 7, provided with right andleft hand threads, denoted by 28 and 29, adapted to engage'gears 26 and25, respectively, is rotatably against longitudinal at 30 and 31 in Fig.1, and a beveled gear 32 fixed to the lower end of the driving screw isadapted to mesh casing in any desired manner, as at 35. An is rigidlysecured to the 3'? denotes a shelf which extends between the side wallsof the casing and preferably slants downwardly toward roll 17 about asshown. in Fig. 2, and 38 denotes a drain shelf adapted to receive themeat after the blood has been expressed; Either or both of thesefeatures can be dispensed with when this is found desirable.

ihe operation of expressing the blood is extremely simple. After therolls have been adjusted the desired distance apart, the meat is placedon the shelf and moved to position between the rolls. When now thehandle is turned in proper direction the driving screw 1s rotated andthe rolls are caused to turn in opposite directions sothat they grip themeat and cause it to be fed through and onto the drain shelf, as will beunderstood.

Thepressure of the rolls on the meat expresses the blood which passesthrough opening 11 into the container. The adjustable roll can' be setfor meat of any desired thickness,and by the proper adjustment of saidroll, any desired pressure can be had on the meat. The rolls can ofcoursehave working faces adapted to p1erce,-mash, or

' otherwise soften the meat without expressing the blood. [As shown,'theworking faces It will be apparent that ii. found desirable, the rollsand their associ= are serrated.

ated parts can be constructed o that they will be removable from thecasing.

.At A- in Fig. l l have indicated a clamp of" any desired constructionand by means of which the device can be supported from a table. or thelike.

While I have shown and described one particular way in which theadjustable rolls and their driving means can be incorporated in thecasingito accomplish the ob ects of the invention, it 'is tobeunderstood that the construction and arrangement oi parts d1s-' closedmay be varied within the spirit of the i vjention and the scope of theclaims.

f hat I-de'sire to claim is: r

1. A device for expressing blood from meat, comprising a casing, .rollsmounted therein and adapted to be ad usted iromand toward each other,gears carriedby the rolls, andmeans whereby the rolls can be rotated inopposite-directions, said means including a driving screw ada ted toengage said gears,

I 2. A devlce for expressing blood from meat, comprising a casing, rollsmounted I therein and adapted to be adjusted from and tow'ard eachother, gears carried by the rolls, meanswhereby the .rolls can berotated in opposite directlons, said means ineluding a driving screwadapted to engage sa1dfgears,and a container located beneath said rollsand detachably connected to said casing.

3. A device for expressing blood from meat, comprising a casing havingparallel side walls each provided with a slot, rolls .mounted in saidside walls, one of said rolls adjustable in said slots rrom and towardthe-other roll, and unitary means for cans ing said rolls to be rotatedin opposite d1- rections for the purpose specified. V

4;. device for expressing blood from 'meat, comprising a casing havingparallel comprising a casing having a continuous wall leadingto anopening, rolls mounted in said casing and adapted to be ad usted fromand toward each other, and means for rausing said rolls to be rotated inopposite directions, said means including gcarsrcarried by said rollsand a driving screw'meshing with said gears. V i

G. A device of the character described,

comprising a casing having a continuous wall leading to an opening, acontainer beneath said opening and adapted mbe detachably connected tosaid casingprolls mounted in said casing .and adapted to be adjustedfronrand toward each other for the purpose specified, and means forrotating said rolls in opposite directions, said means comprising gearscarried by said rolls and a driving-screw 'providedwith right and lefthand threads, one of sald threads engaging each of said gears.
